I am intrigued yet naive to OpenZFS. Are you able to elaborate? I’m a beginner in this area. ---

Happy to: It would be better to explain a little about your system first. It will make things more straightforward since it would be a targeted conversation. Alan will also chip in I’m sure. If you want to keep your specifics private you can send me a direct message or an email. [phil\_man@mac.com](mailto:phil_man@mac.com) ---

Ok Give me a while to drag up all the system details and build a spreadsheet. What kind of reliable throughput (write/read) are you currently getting and how are you networking to date? ---

Off the top of my head… The 32TB Pegasus is 535MB/s write and 160MB/s read The Thunderbay RAID 6+ is 512MB write and 1660MB/s read The NVME raids are about 6600MB/s read and 7600MB/sec write 10GB networking. The 32TB Pegasus I’d rather not touch right now…thats got a bunch of stuff on it that keeps me workin. The Thunderbays I have the data elsewhere local and offsite so those could be the experiment. ---

Ok Good to know Gigabit networking? 10Gb networking? ---

And I can donate 1 of the NVME RAIDs to science this right now, as its not booked coming up this week. ---

Are your machines the new format Mac Pro? Is networking native or on PCIe cards? ---

I’m dragging all of the details out of every Mac dot com Then I’ll drag all the details for the storage Then I’ll pull the ideas for openZFS Give me a little while. The good news is that your gear is all documented and tested. (Unlike M1 chips) ---

Ok I’m just waking up on this west coast Do you have both of thes enclosures connected to one workstation? Does your network switch support bonding? Do you have flash drives for both of your thunderbolt enclosures? ---

The 16core has them direct attached. No flash avail in those enclosures. Bonding capability is unknown. [https://www.ui.com/unifi-switching/unifi-switch-16-xg/](https://www.ui.com/unifi-switching/unifi-switch-16-xg/) ---

Ok let me look up the switch Meantime can you look up compatible flash from OWC (small quantities like 32GB or 64GB) because you can use them as write caches (ZIL for zfs) I checked to see if Nic teaming is back on apples menu and it is. I harbor an idea that you should be able to get roughly 750 Megabytes/s read and write to and from your enclosures and 20Gigabits per second to and from each Mac. Grab the openZFS installer for Big Sur from the openZFS website. You may want to sell your ram and buy a bigger set. Like 384 gigabytes or something. OpenZFS will use all available ram and once data is in Ram it moves faster than nvme . [Next page](https://forum.logik.tv/t/openzfs-crash-course/2380.md?page=2)
